Vertical Situation Display (VSD) - Flight Path Background
1 MCP Selected Vertical Speed (V/S)
Displays the selected vertical speed as a dashed target angle line when the MCP
V/S mode is selected.
2 Vertical Flight Path Vector
Indicates current flight path angle as a function of vertical speed and ground
speed. The length of the vector is fixed at one half of the VSD range.
3 Range to Target Speed Dot (RTSD)
Indicates where the airplane will achieve the FMC or MCP target speed.
• dot is blanked within 5 knots of target speed
• dot reappears if speed increases 10 knots or more faster than target
speed
• replaced with an unfilled dot at vector end if target speed will not be
achieved within length of the vertical flight path vector line.
4 3-Degree Reference Line
Displayed for approaches that do not have a designated approach angle.
• dashed line extends 10 NM for situational awareness
• anchored to the runway threshold
• for reference only, line may intersect terrain.
5 Decision Gates
Displayed on the FMC approach glide path angle line or 3 degree reference line at
500 feet and 1000 feet above field elevation.
6 Runway
Represents the selected runway.
